this is very good. It’s just missing one thing. the export command should be added in in the

/.bashrc file to survive across sessions.
$ tail -1

or the equivalent for your chosen shell (bs, ksh, tcsh etc …)

Just the solution I needed to figure this out, thanks man! 😀

Nice.
For compiling C prgms,
cc hello.c
./a.out

btw, Why don’t you have categories in WP?

Click on category icon (hint: Bash shell).

Hello Vivek, I was not aware that that image is a category link, too 🙂 It really looks like a post image. I’m referencing this site from time to time, and I’ve learned that you have categories just now! I’d really suggest using a different method for showing categories, unless you want to hide them 🙂 Thanks for the great site.

Please provide the info..

How to run the Unix command only during the even and odd hours only.

Kindly provide the command to incorporate in the script.

Hi,
I am having a problem related to this. I have downloaded an program and it has a GUI written in Java. I need to run the script to launch this program, with “sudo” privileges in order to having it running properly. I don’t want to navigate to the folder where this script is, every time I need it, therefore I first made it executable and added the folder to the PATH. Now, when I write “sudo script-name”, I get “script-name not command found”, if I write only “script-name”, it finds it but it doesn’t run properly. Is there a way to launch a script, that is in the PATH, with sudo privileges? Thank you in advance.

Run it as follows:

Or cd to /home/foo and run:

Thank you. I decide to add it as an alias: “alias script-name=’sudo bash /path/to/script/script-name”

What’s the difference with §. /PATH/TO/TARGET§ and §./PATH/TO/TARGET§ ?

thanx, im learning and your are a good teacher.

date -s “2 OCT 2006 18:00:00”

if we want to install software from cd.. how should be the command? i’m the newbie

rashid, if you want to install software from the cd you should try synaptic package handler or apt-get .

if the software is usually from the cd it will tell you to insert it

How can i execute this command export PS1=”\[[33[01;32m\]\u@\h\[33[01;34m\] \W]\]#” from a .sh script for example and make it work ?

Hey Black_Ps`
There are a few ways to do this but if you are not familiar with some of the nuances of Linux, it might be easier to create a new folder to place the file in (or all of your scripts in) like home/username/Desktop/scripts (substituting the actual user name in place of username). The following instructions are based on Fedora 10 with GNOME desktop so if you are running a different Linux distro, you may or may not have a few slight variances. Once you have a good place to store your scripts, you can use the GUI to help with creation of the shell script. Next, click on the “Applications” menu and highlight “Accessories” and then select “Text Editor” Type the following command #!/bin/bash and then press the enter key. Now, type the command you listed into the text editor and then select the “Save As” option. Now name your file (highly recommended that you don’t name it with spaces and make the name all lower case to help with ease of use later) and save it to your new folder you created…remember to give it a .sh name extension. Now close the text editor and go back to the “Applications” menu and highlight “System Tools” and then select “Terminal”. Type the following command cd /home/username/Desktop/scripts (again substituting the actual user name in place of username). The command ls and then press the enter key. Did it return the name of your script as a file in that folder? If so, move on to the next step. If it did not, navigate to the folder where you saved this file and move it to the correct folder. Type the following command chmod 755 yourfilename.sh. That’s it, you now have an executable shell script that will execute your command. You can do so by double clicking on it from the GUI, calling it from the terminal like so bash /home/username/Desktop/scripts/yourfilename.sh or you could put it on the cron to run unattended if you needed to. I hope this helps some or at least points you in the right direction.

can you please expalin it more detailes.
